To all whom it may concern: it known that I, FRANK V. COLLINS, a citizenof the United States, residing at Manistee, in the county of Manisteeand State of Michigan, haveinventeda new and useful Air and LiquidSupplying Device, of which the following is a specification.

The present invention appertains to a device for supplying airandliquids to internal combustion engines, and aims to provide a novel andimproved device of that character, the introduction of the mixture ofair and suitable liquid in the cylinders of they engine having theadvantages of removing. and eliminating carbon in the cylinders and onthe valves, and increasing themileage per unit of fuel for increasingthe efliciency.

The invention has for its object the .pro vision of a pipe having meansfor holding a suitable liquid or liquids, means for the admission ofair, means for controlling the flow of air, and means for controllingthe flow of liquid whereby the desired resultscan be obtained.

It is also the object of the invention to providean appliance of thenature indicated which is comparatively simple and inexpensive inconstruction as well as being serv iceable and eflicient'in use.

\Vith the foregoing. and other objects in view which will appear as. thedescription proceeds, the invention resides in'the combination andarrangement "of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the precise"embodiment ofthe invention herein disclosed can be made within the scopeof what is claimed without departingtfromthe spirit of the in-'vention'. V

'The invention is illustrated in the accompanying drawing, wherein:-

Figure 1 is avertiea'l median sectionot the device, portions being shownin elevation. 1

Fig. Qis an enlarged sectional detail taken on the line "2-2 of Fig; 1.

The receptacleor reservoir for the'liquidl is designated generally bythemumerat and has transparent side walls, said recep-v tacle beingcomposed of an" uprightcyliir' drical glass bodyfZ and bottonr and topplates 8 and 45 between which the body 1 is clamped. The receptacle iscovered, and ex-' cludes'free ingress andfeg ress ofiair above the 7liquid level." The bottom plate: h as a central upstanding tubularmember: 5- 'hav-m ing its upper end threaded within a dependngcentralboss 6 with which the top'plate' 4 is provided, whereby to drawthe bottom and top plates toward one another to clamp the body 2. Thetopplate at has a filling opening '8 normally closed by a removable plugor. cap 7, which when removed enables the liquid to be poured into thereceptacle.

' A vertical tubular valve 9 is mounted for rotation within the tubularmemberb and extends through the boss 6 and top plate 4:

i which are provided with an aperture or bore for accommodating saidvalve, the lower end of the valve seating upon the bottom plate 3. Thevalve 9 has an upwardly facing shoulder 10 seating against a downwardlyfacing shoulder 11 with whichthe top plate is provided, whereby toprevent the upward movement of the valve, and the valve has a tubularstem or reduced portion 12 protruding from an upstandingboss 14 withwhich thetop plate 4 is provided. A suitable handle or finger piece 13is secured upon the stem 12 for turning the valve, and a gland 15 isthreaded upon the boss 14% around the stem 12 to prevent leakage. Thetubular member 5 and boss 6 are provided with apertures 16 adjacent toand midwaybe' tween the top and bottom plates, and the valveQhascomplementary lateral apertures 17 to move into and out ofregistratloii with the apertures 16, whereby to establish and cut offthe communication between the interior of the receptacle and bore of thevalve 9.

The bottom plate 3 is provided with'an upstanding tubular member 18within the member 5 and of much shorter length, and said-member 18 isprovided 111 one side wall with an aperture 19. The bottom plate 3 has avertical bore or duct 20 extendingfrom the lower end of the chamber ofthe meniber 18 through adepending boss 21 with which the bottom. plate 3is provided and to the tip of a depending nipple 22 with which the boss21 is provided. A vertical needlevalve 23 extending through the valve 9axially thereof'is threaded, as at 24,:adjac'ent'to its tip within theend of the. meni-- ber 18 for adjusting'theneedle valve, and the bottomplate 3 hasaseat 25 at the juiici ture of the member 18'and bore 20witlr which the lower end or tip of the needle valve 28 "is cotiperable,for regulating the flow of air and-liquid from the'aperture 19 into thebore 20. The stem 12' has a reduced portion 26 through which the stem ofthe needle valve 23 projects upwardly snugly, the upper end of theneedle valve having a hand wheel or disk 27 for screwing the needlevalve upwardly and dowi'iwardly. gland 28 is threaded upon the upper endof the stem 12 around the needle valve stem to prevent leal'rage, and acurved leaf spring" 29 has its basal end fitted upon the bossv 14 andclamped against the top plate 3 by means of-a nut 30 threadedupon theboss. The free end of the spring 29 is engageable with the hand wheel 27to .hold the needle valve in anyadjustment.

A depending air, inlet tube 31 has its upper end attached to the topplate 4, and 1ts lower end terminates within the receptacle near thebottom plate whereby to admit the air at the lower end of thereceptacle, and requiring the flow of the air through the liquid. toreach the air space at the upper end of the receptacle. A suitable valve32 is attached to the plate 4 in communication with the upper end of thetube 31, in order that the flow of air into the receptacle can beregulated or stopped.

A sight feed cup 33 has its upper open end threaded or otherwise engagedupon the boss 21 to inclose the nipple 22, and a seat 37 and incloses aball valve 38 which is seatable upwardly against the seat 37 to act.

as a check valve for preventing the reverse flow of fluid. The valve 38is prevented from falling from the nipple 36 by means of a diametricalpin 39 provided within said nipple.

In order to admit air andpriming fuel into the manifold and. cylinderswithout passing through the liquid in the receptacle,

the bottom plate 3 is provided with acradial bore or duct 40 extendingfrom the bore 201 to-the' margin of the plate 3, and to which the valvecasing 411's attached in communicationwith the outer end of the bore 40.

. The valve casing 41 has an upper inlet portpriming fuel canbe pouredinto the port 42 7 42, and a needle valve 43 is threaded within thecasing 41 to regulate the flow of air or liquid from theport 42'into thebore 40. In starting'the engine, gasolene. or other to flow'into thecylinders, and; if desired, a priming fuel cup or funnel can be appliedto the valve casing 41 to facilitate the pouring of the fuel intothe'device, the fuel flowing from the valve 41 through thefbores orducts'40 and 20 and through the nipple 36. In use, the nipple 36 isattached to theintake manifold, and a suitable liquid or liq ulds 1spoured lnto the receptacle, for example, kerosene or water, orequalparts of V The introduction of vapor into the both. cylindersis'beneficial, for the purpose of eliminating carbon and preventing theac cum'ulation thereof, and the introduction of kerosene .hasrecognizedbeneficial results, to

in any adjusted position by means of the spring 29, while the tubularvalve 9 can be oscillated manually by means of its handle orfinger piece13. Supposing that the engine is in operation, with the valve 23 openedthe desiredamount, and the valve 32 opened .to admit air, the valve 9can be oscil-' lated to bringthe apertures 16 and 17 into and out ofregistration, thus intermittently establishing communicationibetween theinterior of the valve 9 and the liquid chamber of the receptacle. Thevalve 9 is only allowed to remain open momentarily, and it can be openedand closed as many times as deemed advisable by the operator, when it isdesired to introduce the water vapor and kerosene into the engine atintervals. When the valve 9 is open, the suction created by the enginewill extend through the sight feed chamber, bore 20, aperture 19,

tubular valve 9, and apertures 17 and 16 into the liquid receptacle,whereby air and liquid will be drawn from the receptacle into thetubular valve and thence to the manifold by way of the aperture 19, bore20 and sight feed chamber. The air in the upper portion of thereceptacle will flow more freely through the uppermost apertures 16 and17 into the tubular valve 9, whereby air is drawn into the receptaclethrough the tube 31. Theair which enters the receptacle by way of thetube31 flows upwardly through the liquid and becomes saturated, althougha small quantityof liqui-d flows through the intermediate and'lowermostapertures 16 and 17 into the valve 9 to mix with theair whichflows'downwardly therein at a considerable velocity; Thus, a greaterquantity of: air is'drawn from the receptacle into the. valve 9 than theliquid, and this flow of airand-liquid is shut off immediately when thevalve 9 is closed, said flow being reestablished when thefvalve is againopened.

The flow of air intothereceptacle from the In this way, the ,liquid.wh1chenters' the valve 9 is. drawn ofi", through the bore, 20, topreventthe accumutube 31 serves. to agitate the liquid thereinand entrain theparticlesof the liquidi" An additional supply of air cant-be provided byopening the valve 43, which will not be interfered by the closing of thevalve 9. When both water and kerosene are used, the latter will remainon top of the water, so that the water can pass through the lowermostapertures 16 and 17, while the kerosenecan flow through the intermediateapertures 16 and 17, it being kept in mind that the air will flowthrough. the uppermost apertures into the valve 9.
